    照明光源的頻閃對視功能的影響
  5. The innovative idea of the method is in that the analytic ability for high - frequency signals of wavelet packet is used to enhance information capacity. because the human vision is insensitive to high - frequency signals, one can make information of watermark mass and hightensile in the high - frequency domain. in this way, not only the quality of original image can be reserved, but also the robustness of the watermark improved

    其創新點就在於利用小波包對高頻信號進一步分解的能力，極大地拓展了信息嵌入的空間，由於人眼視覺對高頻信號的不敏感性，可以以較大的強度在高頻部分嵌入水印，這樣不但可以保證原圖質量，而且可以進?步提高水印的頑健性。
  6. Baesd on the theory that moving target detectability can be enhanced by joint space - time processing with the application of frequency features and targets " characteristics, we focus our attention on particularies of sonars " target detection using underwater acoustic techniques and vehicle detection using computer vision techniques

    本文注重在理論指導下的特殊性研究，即在聯合利用時間信息、空間信息、頻率信息以及目標特徵能夠提高運動目標檢測能力的思想指導下，分別研究了聲納的運動目標檢測和基於計算機視覺的交通車輛檢測。
  7. 3. scan frequency is over 200hz : using over 200hz frame scan frequency will have good vision effect

    3掃描場頻大於200赫茲：使用幀掃描頻率200hz以上，有很好的視覺效果，人肉眼幾乎
  8. Comparing with the image watermarking, the audio watermarking have a few characteristics : 1. comparing with the visual media, audio frequency signal has less sampling points at every time interval. 2. owing to human audition systems, it is more sensitive than human vision systems, therefore, it is more trouble to realize the imperceptibility of audition compared to the vision systems. 3. to stick up to the cut attack, embedded watermark should keep synchronization. 4. because of the bigger memory payload of audio frequency signal, the initial audio frequency signal must be removed during the extract in order to protect the maneuverability of project

    數字水印技術是近幾年來學術界興起的一個前沿研究領域，提高演算法的魯棒性、安全性、實用性是數字水印的研究方向。本文提出的基於可視密碼術的小波域下量化系數的魯棒性音頻數字水印方案，其優點在於利用小波變換的多解析度特性在保證水印魯棒性的同時使水印對原始音頻信號的影響達到最小，採用量化系數的方法嵌入水印信息實現了盲水印，提高水印的工程應用價值。
